Abstract

Floods are natural disasters that often occur in Indonesia, one of them in Gorontalo Province. Flood handling must begin with an understanding of flooding and geological conditions that have the potential to cause flooding. This study aims to determine the causes of flooding that occurred in the Ilotidea area based on the analysis of SRTM radar image data. SRTM data is processed and produces a 3D watershed hydrology surface model. Hydrological modeling is then carried out to obtain a 3D hydrological model on the surface of the Ilotidea region and its surroundings. Analysis of 3D watershed hydrology models and 3D hydrological models on the surface of the Ilotidea region and beyond to determine the causes of flooding in the Ilotidea region. Based on SRTM data, Ilotidea region consists of mountains morphology and lake plains. Surface modeling of 3D watershed hydrology shows that the Ilotidea region is in the Bolango watershed. The hydrological 3D surface model of the Ilotidea region shows that the flooding was caused by the overflow of Limboto Lake and Bolango River. Based on the results of the study, it can be concluded that when high-intensity rain occurs it will cause Limboto Lake and Bolango River to overflow, then causing flooding in the Ilotidea area.

Abstract

Geology is an important aspect in the development of tourism in an area. One of the attractions in a natural tourism location is certainly highly controlled by the geological setting in the area. The purpose of this research is to assess tourism values of geological features in the Bongo and surrounding areas as a basis for developing geotourism on the southern coast of Gorontalo. The research location is at coordinates N 00029’42” - N 00029’51” and E 12301’26” - E 12303’32”. The method used in this study is a surface geological survey, which includes field data collection in the form of lithology, geological structure and geomorphology. The standard used for assessing tourism values is the technical guide for assessing geological heritage resources by the Geological Survey Center. The results showed that the lithology unit of the study area consists of granite, volcanic breccia and reef limestone. The geological structure in the research area is shear fracture with main stress that relatively directed to northwest-southeast. The geomorphic unit of the study area consisted of two units, namely volcanic hills, and marine units. The results of the assessment of tourism values on geological features explain that the Bongo and surrounding areas are included in the medium category. Improvements are needed on low value criteria, namely vulnerability, relationships with other values, and economic level.

Abstract

Regionally, the research area is composed of volcanic and plutonic rocks. Stratigraphic data of the study area are still regional scale. This study aims to analyze detailed stratigraphic data and formulate the geological history of the Limbato area and its surroundings. The area located at coordinates 0º56’6” - 1º0’10.8” N dan 122º5’56.4” - 122º9’10.8” E, the area of the study is around 45 km². The method used in the research is scientific exploration by conducting a surface geological mapping survey. The geological surface in the form of field data collection and laboratory analysis. Field data in the form of lithology data and laboratory analysis in the form of petrology and petrographic analysis. The stratigraphy of the research area is divided into 4 (four) unofficial units, which are sorted from old to young, namely granodiorite units of Middle Miocene age, volcanic breccia units of Late Miocene to Early Pliocene, andesite units of Middle Pliocene and alluvial units of Holocene age.Stratigraphic analysis of the Limbato area is related to geological history. In the Middle Miocene period subduction formed plutonic rocks that produced granodiorite units, then during the Late Miocene volcanic eruptions resulted in volcanic breccia units. The activity was stopped at the time of the Early Pliocene. After the volcanic activity was stopped, then new magma activity occurred at the time of the Middle Pliocene resulting in an andesite unit. After all rock units have been deposited, an erosion process occurs in older units which results in an alluvial unit.

Abstract

The research area is located in South Leato, Dumbo Raya District, Gorontalo City. The research area is consist of Bone Diorite Formation which is in the miocene and the Pinogu Volcano Rock Formation which is in the quarter. The geological structure of the study area recorded in different rock formations is very interesting to be studied. The purpose of this study is to identify the types and general directions of geological structures that control the stress regime in the study area. This research method is in the form of field data collection and studio analysis. Data is collected by the field survey method. Analysis studio in the fracture processing data. Based on observations in the field, the geological structure contained in the study area is controlled by fracture. The type of fracture in the field is shear fracture. The results of the reconstruction of shear fracture in the study area is relatively northwest-southeast and north-south main direction.
